Run against Obama

When a Republican has been in the presidency for eight years, as George W. Bush was, Democrats run against the Republicans. When a Democrat has been in office for eight years, as Barack Obama will soon have been, Republicans run against Republicans.
This is a year in which the multiple failures of the Obama years should be irresistible for Republican presidential candidates. Democrats, correspondingly, should be awkwardly sidestepping and tightrope walking to avoid a too-close association. Instead, partly due to the eccentric obsessions of Donald Trump, we've seen Republicans reprising debates about the wisdom of the Iraq War while ignoring the greatest foreign policy debacles of the Obama years. If the Iraq War was a mistake of over-engagement (and there is a good case that it wasn't), Syria illustrates the perils of under-engagement — hundreds of thousands killed, a region destabilized, the metastasis of ISIS and the worst refugee crisis since World War II.
